This application claims priority of U.S. Provisional Application Ser. No. 60/570,788, filed May 13, 2004.
Each day more than 200,000 United States Postal Service (USPS) carriers deliver mail to approximately 100 million individual domestic addresses. Much of this mail is delivered via a park and loop method wherein the mail carrier drives to a location on his or her route, separates mail destined for a particular loop of addresses and walks the loop, delivering mail pieces to addresses on the loop. Other mail is delivered via the curbside method where the carrier drives his route, stopping to deliver mail pieces to individual addresses.
The mail delivered by the carriers typically comprises letters, flats (including enveloped and non-enveloped magazines) and parcels. As used herein “letter sized” or “letter” generally refers to envelopes, postcards and similar mail pieces having dimensions up to about 6″×11″. “Flats” as used herein generally refers to larger, flat mail pieces having dimensions larger than about 6″×11″ and having a thickness up to about 0.75″, and includes catalogues, magazines, larger envelopes and similar items.
Currently, the carrier normally assembles one or more stacks of letters, flats and parcels and places the individual mail pieces in delivery order or another appropriate sequence for efficient delivery. At each address the carrier riffles or thumbs the stack or stacks, finding the first and last letter addressed to the address selecting the items for that address. The mail carrier places these mail pieces into the postal patron's mailbox and repeats the operation for the next address. Sorting or riffling through the stack or stacks of mail is time consuming and inefficient. Consequently, any reduction in the amount of time required to separate the mail for delivery presents an opportunity for increased efficiency.
In Pippin et al. U.S. Patent Applications 20020031284, published Mar. 14, 2002, and 20040168993, published Sep. 2, 2004, a mail case system facilitates sequence-sorting various types of mail together into individual bags that each represent unique delivery points. The mail case uses multi-bag inserts so that the bags for several stops can be set up quickly for sorting. At the end of the sorting operation, the entire insert may be pulled down from the case as a single unit to maintain the established delivery point sequence. This eliminates the carrier's need to find separation points or to combine selections from multiple sequenced stacks of mail during the delivery operation.
Edmonds U.S. Patent Application 20030208298, Nov. 6, 2003 describes a sorting and packaging system comprises an induction and scanning system, a single pass sorting and packaging system for automatically sorting and packaging a plurality of mailpieces based on a single scan by the induction and sorting system, and a control unit connected to and controlling the induction and scanning system and the single pass sorting and packaging system. The single pass sorting and packaging system comprises at least one cell rack, at least one packaging system, and at least one delivery system. The package may comprise a bag removably surrounding the at least one mail piece addressed to a specific address.
The use of bags for packaging mail for delivery remains problematic in view of the potential cost of such bags, the difficulty of getting the mail into a bag, and the recycling problem presented by the large number of bags that would be required. The present invention addresses these difficulties.
A mail holder according to one aspect of the invention includes a series of flexible plastic divider sheets each having a handhold opening near an inside edge of the sheet and means for uniting the divider sheets in a stack along the inside edge with the handhold openings substantially in registration with one another. The handhold opening enable a user to turn over a topmost one of the divider sheets with one hand while holding the mail holder or mail contained therein with the other hand positioned in a handhold opening. The uniting means may be an accordion style spine, a single edge spine, rings that hold the divider sheets together in loose leaf fashion, or fasteners such as clamps. In one aspect, the spine is interrupted at the handhold openings, forming spaced, inner and outer spine portions on opposite sides of the handhold opening. In another, an accordion style spine has at least one fold line parallel to the inner edges of the sheets between adjacent pairs of divider sheets, permitting the mail holder to collapse accordion style. In another aspect, the mail holder is provided with top and/or bottom cover sheets that are stiffer than the divider sheets.
A method of the invention for manually distributing mail from a mail holder that includes a series of flexible divider sheets each having a handhold opening near an inside edge thereof and one or more mail pieces inserted between each of the divider sheets, wherein the mail pieces are separated into delivery groupings by the divider sheets, includes the steps of: (a) turning over a topmost one of the divider sheets with one hand while holding the mail holder or mail contained therein with the other hand positioned in a handhold opening, (b) removing mail that was beneath the topmost divider sheet; (c) placing the removed mail into a mail receptacle, (d) then repeating steps (a)-(c) for the next divider sheet and mail beneath that divider sheet, wherein the mail receptacle is different for each repetition of steps (a)-(c), until all mail has been removed from the mail holder. In one variation, the method includes the step of loading mail into the holder according to a predetermined delivery scheme. In this regard, the mail may be loaded into the pockets of the holder in delivery point order.
In another aspect, the invention provides a system for manual delivery of mail to a series of recipients, includes a stack of mail holders in the form of folders each comprising a front flap, a back flap and a central fold with one or more mail pieces disposed in each folder. All of the mail pieces in each folder are to be delivered to the same recipient, and the folders are stacked in a predetermined order for a carrier delivery route. The folders may be provided with areas of releaseable contact adhesive on the inner faces of the front and back flaps to aid in retaining mail pieces therein. Each folder may have also have the address of a recipient of the mail pieces printed on an outside surface of one or both of the front and back flaps to facilitate delivery.
In yet another variation, the invention provides a method of manually distributing a batch of mail to recipients having addresses on a carrier delivery route, including the steps of: (a) placing mail pieces for delivery to each address along the carrier route in a series of pockets formed by mail holders with mail pieces for delivery to each address being placed in a separate pocket, each of the mail holders having the address of the recipient of those mail pieces printed on an outside surface of the holder; (b) stopping at an address corresponding to an address on a holder; (c) selecting the holder for that address; (d) one of:
As illustrated, divider sheets 12 may each include a tab 18 for labeling the individual sheets with an address or other information. A cover 20, also formed from a material such as polyethylene or polypropylene supports holder 10 when in use. Cover 20 should be sufficiently rigid so as to prevent holder 10 from buckling when the holder is fully loaded with mail. One or more transparent pockets 24 may be formed on the outside surface of cover 20 for labeling purposes such as identifying a series of address corresponding to a delivery loop.
As best illustrated in
Typically, a carrier will load mail in delivery order in pockets 26, with the mail for the first address in the upper most pocket. The carrier registers or aligns the end of each mail piece 15 against spine 22 with the lower edges 19 of mail pieces 15 being substantially aligned with the near edge 28 of divider sheets 12. The near edge 28 of divider sheets 12 is the edge of the sheets closest to the carrier's body when holder 10 is held as illustrated in
Referring now to
Since the mail carrier may rely on tactile sensation to distinguish between divider sheets 12 and mail pieces 15 when walking between addresses, sheets 12 preferably have a surface texture that is sufficiently different from the surface texture of mail pieces to enable the mail carrier to distinguish the sheets from mail pieces 15 by means of touch. Sheets 12 may be also colored in such a fashion as to distinguish the sheets from mail piece 15 carried in holder 10. Sheets 12 may also be transparent or opaque. Since the carrier has already loaded mail for individual addresses in delivery order in pockets 26, the carrier does not need to visually inspect the mail pieces in order to separate mail for different addresses. The use of opaque divider sheets 12 may also prevent the tendency of the carrier to examine mail pieces 15 carried in holder 10.

In some instances it may be preferred or desirable to employ divider sheets having geometries other than rectangular.
